[Termes IGN] traitement de données localiséesRésumé : (auteur) Currently, there is a multiplicity of geographical information to describe the same reality. Nevertheless, we realise that there is independence between databases that represent the same reality and this affects both data users and producers. Integration seems to be the issue to that problem. One of the steps of the integration process is the data matching process that furthermore represents our issue. The purpose of this paper is to define a data matching approach based on the Theory of Evidence. The goal is to model explicitly the imperfection and to fusion many criteria of data matching in order to improve the quality of the results. Our approach is carried out in threes steps, consisting in computing the basic belief masses and fusioning criteria and assumptions. The basic belief assignments for each source are modelled in order to allow to weight a possible matching and to weaken it, in the contrary case. Fusion process based on combination of distinct sources may generate conflict. In this paper, different operators are tested in order to manage conflict and we show that the choice of an appropriate operator is crucial.
